Overview

XC25BS8 Series is Not Recommended for New Designs.
XC25BS8 Series ETR15006-011 Ultra-Small PLL Clock Generator ICs with Built-In Divider/Multiplier Circuits ■GENERAL DESCRIPTION The XC25BS8 series is an ultra small PLL clock generator IC which can generate a high multiplier output up to 4095 from an input frequency as low as 8kHz.
The series includes a divider circuit, phase/frequency comparator, charge pump, and VCO so it is possible to configure a fully operational circuit with a few external components like one low-pass filter capacitor.
The Input divider ratio (M) can be selected from a range of 1 to 2047, the output divider ratio (N) can be selected from a range of 1 to 4095 and they are set internally by using laser timing technologies.
Output frequency (fQ0) is equal to input clock frequency (fCLKin) multiplied by N/M.
Output frequency range is 1MHz to 100MHz.
Reference clock from 8kHz to 36MHz can be input as the input clock.
The IC stops operation and current drain is suppressed when a low level signal is input to the CE pin which greatly reduces current consumption and produces a high impedance output.
The setting of the input divider ratio (M), output divider ratio (N), and charge pump current (Ip) are factory fixed semi-custom.
Please advise your Torex sales representative of your particular input/output frequency and supply voltage specifications so that we can see if we will be able to support your requirements.
The series is available in small SOT-26W and USP-6C.
